The drills, which began on Tuesday, were the largest of their kind in modern Russia's history and involved nearly 300,000 Russian troops.
China dispatched 3,200 soldiers, along with over 1,000 pieces of weaponry and 30 fixed-wing aircraft and helicopters to participate.
Shao Yuanming, vice-chief of staff at the Joint Staff Department of the Central Military Commission and Chinese chief commander at the drills, said the two militaries deepened their friendship, improved mutual trust and fostered cooperation. The exercises also enhanced the ability of both armies to respond to various regional security threats, he said.
The two nations will continue their military cooperation and explore new possible ways to boost their combat abilities, he said.
During three days of strategic drills, the troops simulated a classic anti-invasion campaign at the training range in eastern Siberia.
Beijing said the drills were not aimed at any third party.
Chinese troops' participation was reported to be their first large-scale overseas military activity since PLA military reforms started in 2016. It also marked the largest military event since Moscow's "New Look" army reform started in 2008.
The two militaries formed a joint operational command system during the drills. Li Weiya, a commander at the Chinese operational command headquarters, said the event has historical significance because it fully demonstrated the new cooperative form and level of the two armies.
He said China's participation shows Moscow and Beijing are now cooperating in all areas.
